(And sometimes developers with moderate<br>experience have to check the documentation as well.)<br><br>After the release of version 3.6 several methods became aware of<br>path-like object. There are only a few ones which does not support<br>the path-like object. After making these methods path-like object<br>aware, these functions could be added to pathlib.<br><br>With functions in pathlib the developers should not have to think<br>on which method (function) can be found in which module.<br><br>Makes the life easier.<br><br><br>Implementation<br>==============<br><br>For compatibility reasons the pathlib should contain wrappers to<br>the original functions. The original functions should remain<br>at their original place. (Or if pathlib contains the function, the<br>original modules should have a wrapper to it.)<br><br><br>List of mentioned functions<br>===========================<br><br> * <a href="http://os.link" target="_blank">os.link</a> => path.hardlink_to<br> (should be named similarly to path.softlink_to)<br><br> * os.mkfifo<br><br> * os.readlink<br><br> * os.remove<br><br> * os.removedirs<br> (shutil.rmtree has the same functionalaty)<br></div></div></blockquote><div><br></div></div>I think you will find these to are a lot different.</div></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">From high level, it is only question of implementation: the main goal is to remove a chain of directories</div></div></div></blockquote><div><br></div>This is a PEP you and proposing details matter and this is one of the details tha you need be clear on.<div><br><blockquote type="cite"><div><div dir="auto"><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto"><div><br><blockquote type="cite"><div><div dir="ltr"><br> * os.truncate<br><br> * shutil.copyfileobj<br></div></div></blockquote><div><br></div>This function does not take paths as arguments.
